Application filed October 27, 1911. Serial No. 6.73034.

To all whom it may concern:

Be it known that I, HOWARD K, Kim}, a citizen of the United States residing at Philadelphia, in the county of hiladelphia, State of Penns 'lvania, have invented a new and useful Follli11g=Machine, of which the following is a specification.

M invention relates to improvements in sheel folding and lnsetting machines.

My object is to provide improved means whereby a. sheet is given a required number of folds, then cut into sections, and sections folded and one delivered independently or else suyerimposed and insetted one section within another.

The invention comprises means whereby the sheet sections are delivered into dii'fen ent planes and then moved forward in ths same direction, cert-sin sheets into the fold ing position, and then other of said sheet sections are moved transversely into the folding position.

The invention comprises means whereby each sheet section is struck seperately through the last pair of folding rollers, or else two su erimposed sheet sections are struck toget. through the final. folding roliers so that one may be insetted in the other.

Rfifiliflflg to ihe drawings illustrating by way of exaimylesnitebis means for effecting my invention.-.-F1gnre l s s plan v ew. Fig. 2 is a vertical sect on on line fie- 2 01? Fig. 1. Fig. 3 is sverncal section on line 33 of F 1. Fig. is a. fragmentary plan View of a, cutting roller and associated mwhnnism, Fig. 5 a. vertical section on line 5'5 of Fig. Fig. 5 is a. vertical section on line .6 8 of Fig. 4. Fig. 7 is a sectional detail on an eninrged scale of the striking blade and folding rollers. Fig, 8 is a front elevation of the cam for actuating the insetting striking blade. Fig, 9 is a side elevation of Fig. 10 55 s, fragmentary detail in section on line 10 10 of Fig. 6, but on e reduced scale.

Similar numerals refer to similar parts throughout the several views.

As a large part of the mechanism utilized for efilect ng the present invention, is not new, it will only be necessary to refer to such parts in indicating the preliminary travei and folding of the sheets. For example, referring to Fig. 2, the sheet is received between the feed roller and the d of roller 21, in the usual we and carrm to position beneath the striking blade 22, by which it is struck between the rollers 23, for the first'fold. The folded sheet is then carried to position beneath the striking blade 25, by which it is struck between the rollers 2 for the second fold. It is then delivered to the cutters 26 and cutting rollers 27, 28 and 291 As will be noted the present machine is provided with three cutters thus serving to out the folded sheet into four parts.

The arrangement of the tapes is such that the two middle ports or sheet sections, 36 and 37, are carried between rollers and 33 onto the tapes and 31, while the two outer sheei: sections 38 and 39 are carried around the cutting rollers 27 and 29 onto tapes 3% and 35, see especially Figs. 4 and 6. It will thus be seen that the outer sheet sections are carried forward horizontally on a plane higher than the two inner sheet sections. Sheet section 38 is carried forward to a point in. the folding position over folding rollers 320 one .1, as shown in 1, while sheet section is brought to s. position over folding rollers 42 and 43. Sheet sec tion carried forward simultaneously before slated, on lower plane but substantially the same distance as sheet section 33, while 5 v ,n ,1. section 37 is sinnisrly carried forward the some distance sheet section 29, out upon a lower plane.

\Vhen it desired to operate the machine to deliver our signatures of sixteen pages each, the machine is operated that the striking blades and 53, Figs. 3 and 7, strike sheet seciions 3S) and 38 through the slits 5i and 54., and the folding rollers 42 and 4?) sod 34) and respectively, while sheet sectiimsilfi end 37 rest in the position shown in Fig. 3%, that is to say, the striking blades 50 and one actuated by the cams 63 and 62 respectively. These cams are each provided with the two dro s or depressions 4 and $5, Figs. 8 and 1). These cams are cared relatively to the cams l8 and 49, whic actuate the drop rollers 45 and 47 respective? which cooperate with the feed rollers .4 and 426, These drop and feed rollers cause the movement of sheet sections 36 and 37 into the folding position beneath said striking blades 53 and'fgt) respectively whereby, upon the next descent of the stril ing blades due to the second recess in the cams 62 and 63, the sheet sections 36 and 37 are struck tl'irough the rollers 40 and 41 and and 43 to receive the-final fold; The sheets struck through rollers #22 and 43 are delivered through the guide slit 56 to the packing trough 57, while the sneets struck through rollers 40 and tl are carried by the tapes 5S and 59 downwardly through the guide slit 60 into trough 61. It is obvious that in such case th packerin these troughs, not shown, is located in the middle, packing the sheet sections 37 toward one end and the sheet sections 39 toward the other end of the trough. In like manner the packer in trough 61 is similarly arranged to pack the sheet sections 36 toward one end andthe sheet sections 38 toward the other end. lVhen however, it is desired that the machine should operate not to deliver four signatures of sixteen pages each, but two signatures of thirty-two pages each, it is simply necessary to prevent the alternate strokes of 'strikingblades 50 and 53, so that the sheets 36 and 37 may be carried by their respective drop and feed rollers beneath sheets 38 and 39 respectively, but in register therewith. This is accomplished by placing a shield 66 in one of the depressions of each of the cams 62 and 63, so that there is one actuation only of the striking blades 50 and 53 with each revolution of its rcspcctn'e actu ating cam. That is to say, after the sheets 36, 37, 38 and 39, all reach the position shown in Fig. 1, there is a pause in the operation of the said striking blades 50 and 53. until 37 is brought beneath 39, and 36 brought beneath 38, whereupon the striking blade 50 strikes 39 through slit of plate 51 and then carries it with sheet 37 through slit members 52 and folding rollers 4-2 and 13, thereby folding 37 with 39 insetted. In a corresponding way 36 is folded with 38 insctted, in which case the packers in the packing troughs 57 and 61 are arranged to pack the signatures in each trough all together in one direction.

The operation above described delivers what is called a double 32, that is, two signatures of 32 pages each.

It will thus be seen that by controlling the period of the stroke of the folding blades 50 and 53, is determined whether the said sheet sections are struck individually between the respective folding rollers, or whether the. folding blades pause until 37 and 39 are superimposed and 36 and 38 are superimposed Means for transverse movement of sheet sections 30 and 37.-lt will be understood that after passing the cutters, the several shcet sections move in direction at right angles to the axis of the cutters and cutting rollers, until they reach the positions shown in Fig. 1. It is then necessary to cause transverse movement, in opposite directions, of sheet sections 36 and 37, in order to bring said sheet sections beneath the striking blades 53 and 50 respectively.

Referring to Fig. 3, the sheet sections 36 and 37 are shown in the position at the end of their movement after passing the cutters. The feed rollers 44 and 46 are adapted to act upon the said sheet sections 36 and 37 respectively, causing the movement of the same to the right and left respectively, upon the cooperation with said feed rollers of the drop rollers 45 and 47. These drop rollers are actuated by the cams -18 and 49, 48 only moved by the drop and feed rollers 47 and 46 to the left, along the steel guide 81, until said sheet section enters between folding roller 43 and the friction roller 82, whereby it is carried farther on to the left over the slit member 5). between the idler 83 and friction roller 84, along the guide rods 85, until it is brought to rest by the stop 86.

It will be noted that one of the slit incinbo ts 52 has a shield extending to the left ovcr the roller -12. This is provided to prevent the edge of the slicetseetion coming into contact with roller 42, which, traveling in direction opposite to the travel of the sheet section, would tend either to retard the movement of the sheet section, or prematurely to drive it between the folding rollcrs. In orden to make room for this shield extension of the slit member, the top surface of whiclnis substantially in the plane of the top of roller 43, roller 42- is made of lcss diameter than roller -13. To prevent distortion of the sheets passing between folding rollers 42 and 43, roller 4; is driven, by suitable gearing not. shown at a slightly greater angular speed than roller 43, so that the said rollers shall have the same peripheral speed of rotation. Roller 83 is driven in a direction op iosite to that of roller 42 either by direct with, or by suitable gearin The mechanism for causing the transverse movement of sheet section 36 is the same as that above described with respect to sheet section 37.

Adjustablespring controlled yielding saport for outta-r rollers and guide 1=0Zlcrsriction engagement thcre- .[o secure a more uniform pressure between i slidably mounted on the members 69 and 70. To one of these brackets 71 is pivoted the hen er 72 at the point 74 as shown in Fig. 6. In *igY. 5 the hanger indicated by the nu' meral 3, is substantially the same as hanger 72, except it is provided with guides which will be described later on. The hanger 72 carries the middle cutter. The flanking cutters are carried by hangers 73. These hangers 72 and 73 are partially bifurcated and carry the cutting wheels and guide rollers 26. A sprin 75 is connected between the hanger and t e boss 76 on bracket 71. The hanger is also provided with a lug 77 which cooperates with the lug 78 on the bracket 71, for limiting the spring actuated movement of the hanger. It will be noted that there is a sufiicient play between the lugs and the abutting parts to allow a slight rocking movement of the hanger. This gives the necessary yield between the guide rollers and the cutting rollers to assure a uniform feed of the sheets in the cutting operation. It follows of course that Where intermediate or supplementary rollers are used for additional guides to the paper in connection with the cutters or cutter rollers these may be similarly su ported to secure an even feed of all parts 0 the sheet. It is also obvious that the tension of the spring 75 may be adjusted by a suitable screw in lug 76 or by other suitable means.

Lateral adjustment of the cutters and guide r0llers.-In order to conveniently adjust the cutters for different sized sheets the following means have been provided. The machine is provided with a stationary rail 68 running across the machine. On this rail are mounted the sliding members 69 and 70. Upon these members are mounted all of the brackets 71, except the middle one, which is secured on a stationary bracket connected with rail 68. The sliding members 69 and 70 are then actuated by suitable hand wheels and screws as shown in Fig. 4.. It will also be understood that the outer brackets 71 are independently adjustable on the sliding members 69 and 70, so that they may be cor rcspondingly adjusted by slot and bolt engagement for larger or smaller sheets.

Ad'ust'ment of cutting rollcra.--In order to a just the cutting rollers so that their grooves will correspond and cooperate with the cutters, I provide the following mechanism: The shaft 87 carries all of the cutting rollers 27, 28 and 29. The roller 28 is fixed on said shaft while rollers 27 and 29 are feathered on said shaft and are longitudithe bar 68 the rollers are always kept in proper register with their respective cut ting whee Guides for directing sheet section! into difierent planes.-It will be noted that sheets 36 and 37 are delivered from the cutting rollers to a different plane from that to which sheets 38 and 39 are delivered. That is to say, as the original sheet is being cut into the four sheet sections, by the cutting wheels, two sections that is 38 and 39 are guided around cutting rollers 27 an 29, onto the tapes 34 and 35, while the sheets 86 and 37 are guided down between rollers 32 and 33, to a lower plane and delivered onto the tapes 30 and 31. To assure the proper respective travel of the several sheets, I provide, in connection with two of the cutter wheel supports 73, the curved guide 79, on one side of the cutting wheel to direct the sheet around the roller 27 or 29, onto tapes 34 and 35 as the case may be,

while upon the other side of the cutting wheel I provide the guide rod which do fleets the adjacent sheet section downwardly so that it will pass between rollers 33 and 33, that is, these two guides 79 and 80, assure the proper direction of travel of the adjacent sheet sections as the same are being cut and effectually prevent a tendency of the same sticking together or following the same line of travel.
